latitude/longitude and decimal/degrees are read in which directions? right & up or up & right or left & down?

Question

all of the above or none of the above??

Anyone know the answer??

Answer 1

By convention, i.e., what everyone has agreed to, is that latitude is measured relative to the Equator. North of the Equator is north latitude, with 90N at the North Pole, south is similar.

Longitude was defined with 0º as going through Greenwich, England; obviously, the English had a lot of clout back then. By convention, eastward longitude is positive, but generally, we use positive westward longitudes because it's easier.

Answer 2

Longitude is vertical. (Prime Meridian) Latitude is horizontal. (Equator) Degrees are compass headings, which like a circle, (360) can be in any direction that you want to go. 90 degrees is pure East.
